**each asset gets a row here in the same change that adds it.** MaterialCraft's own code and
original assets are MIT OR Apache-2.0 (see [`LICENSE-MIT`](LICENSE-MIT),
[`LICENSE-APACHE`](LICENSE-APACHE) and [`NOTICE`](NOTICE)); third-party assets must be permissively

images, materials, sample graphs, presets, environments) may ever be added.

These come from Rust crate dependencies (not files in this repository) and keep their licenses.

## Procedural content (no asset files)

The node library's noises and patterns (`crates/nodes`), the sample materials and graph templates
(`crates/engine/src/samples.rs`), the 3D view's environments (`crates/render/src/ibl.rs`, procedural
HDR skies and soft boxes), the built-in meshes (`crates/geom/src/primitives.rs`), the library's node
previews (`crates/ui-egui/src/thumbs.rs`, each node cooked on sample noise) and the New graph
dialog's template spheres (`crates/ui-egui/src/windows.rs`) are generated in code by MaterialCraft
contributors (MIT OR Apache-2.0). None of them is derived from another product's presets,
shaders, materials, sample graphs or images.
